The furnished apartment was rented to undisclosed tenants for about six months last year and again for a short time at Christmas.

The Waldorf Towers, which is within the Waldorf-Astoria Hotel, has provided temporary quarters to presidents, Hollywood royals — Brad Pitt, Angelina Jolie and their brood — and actual royalty, including the Duke and Duchess of Windsor.

“There are tenants who have been there for 45-plus years. There are people that come in for the short term,” said Margaret Bay, vice president of Brown Harris Stevens, who handles rentals at the towers.

Porter lived in the Waldorf from 1934 to 1964, but not every unit there is as expansive as his. Studios rent for a mere $9,000 a month.

“If you don’t need the six bedrooms, we can put you in another apartment,” Bay said.
